Detailed Description

used to manually emit particles in case of collisions etc.

This class can handle a number of different emitters which can be registered for a key string. It provides a function (ParticleManager::emit) which allows for convenient particle emission.

Member Function Documentation

void ParticleManager::emit (  const std::string &  name, const G3D::Vector3 &  pos, const float &  dt )

emits a number of particles at the given position This function accesses the emitter registered for name, places it at pos and calls its emit function with the appropriate number of particles. That number is calculated from the emitter's particle emission rate (see Emitter::setEmissionCount) and the frame time dt. This function fails silently if no emitter is found for name. Parameters: name  the requested emitter's key. See ParticleManager::getEmitter pos  the emission center position. Note that particles will be emitted in a certain area around pos dt  the frame step time

ParticleManager::Emitter * ParticleManager::getEmitter (  const std::string &   )

retrieves the emitter for the given key If the key is unknown, a new emitter is created, registered and returned. Note that new emitters are initialized to their default values, particularly, no particle texture is set. See the ParticleSystem documentation and ParticleManager::sort for details.
